The Yamaha TDM is an 849 cc two-cylinder motorcycle, manufactured by the Yamaha Motor Company of Japan, first produced in 1991.

Version History[edit]

The TDM 850 was arguably the first road-oriented "Adventure Tour" motorcycle. It was never marketed as an off-road bike, but as a comfortable yet manoeuvrable all-rounder, rather like the later Honda NC700X, CB500X, Kawasaki Versys, KTM SMT, and Ducati Multistrada. When designing the TDM, Yamaha are said to have used a lot of ideas from their "Morpho" project.[1] The TDM's engine was derived from the Paris Dakar winning Yamaha XTZ 750 Super Tenere. Yamaha intended to create a motorcycle capable of handling the mountain roads of the European Alps and coping with rougher road surfaces; and the TDM's upright riding position was radical in its day.

The TDM was imported into the United States for only two years, 1992 and 1993. It was never a big seller in the United Kingdom or in The Netherlands, but in other European countries (including France, Germany and Greece) sales were strong[citation needed]. In 1996 Yamaha released the Mk2 TDM with updated bodywork and a 270° firing order instead of the previous 360°. This modified engine was first seen on the Japanese market in 1995, when Yamaha introduced the TRX850. The 270° engine gave the TDM an attractive new "feel", and it now became a popular bike in the Netherlands, where for some years it was among the top 15 best-selling bikes.

In 2001 the 3rd incarnation arrived, the TDM 900, with new bodywork, a diamond-shaped alloy frame, a 6-speed gearbox, fuel-injection, R1 derived brakes, a reduced dry weight of 190 kg, a larger-capacity 900cc engine, and slightly wider tyres (160 rear, 120 front). It has a 2-position trip meter, a digital clock, and digital fuel meter. ABS was available as an option.

The TDM is classified as New Sports, a new category invented by Yamaha, comparable with "Dual Sports" or "Adventure Sports bikes". Although a TDM is too bulky and heavy for serious off-road work, its long-travel suspension is well suited for gravel tracks and light off-road use. Popular modifications include fitting aftermarket exhausts, "blue-spot" brake calipers, and dual-sports tires.
